Definitions
- Miscellaneous components which are of a limited size in relation to the tool in its entirety and which require machining to high accuracy are commonly included in tools for chip removing machining, such as milling tools, drilling tools, turning tools and the like.
- tools for chip removing machining such as milling tools, drilling tools, turning tools and the like.
- examples of such components are cassettes and wedges for milling tools, shims for drilling and turning tools, clamps and chip breakers for milling tools, etc.
- Critical surfaces on such components often require tolerances within the range of 0.005-0.02 mm. The same fine tolerances are also required for holes in the components and for serrations, thereon.
- Such components are usually made of steel, which requires hardening.
- the present invention aims at obviating the above-mentioned disadvantages of the previously applied manufacturing method and, in a first aspect, at providing an improved method for the manufacture of components which require chip removing machining.
- a primary object of the invention is to provide a manufacturing method which permits an accurate machining of the requisite blanks without the need to move about between different machining stations and fixtures, respectively, a plurality of components which in all essentials can be machined to completion in one and the same machining station.
- An object is also to provide a manufacturing method, which permits an efficient and thereby inexpensive production.
- the invention also relates to a device for carrying out the method according to the invention.
- the features of this device are defined in claim 8.
- Preferred embodiments of the device according to the invention are furthermore defined in dependent claims 9-11.
- a number of components 1 are shown, of which some are tangentially spaced and located in a ring-shaped configuration, while others are arranged side by side in an axial extension of one of the components in the ring formation.
- these components consist of wedges having the purpose of clamping a cutting insert in a cassette included in a milling tool.
- this type of wedges is delimited by a concavely arched surface 2.
- a blank 3 in the shape of a ring is shown (in a small scale).
- the ring is cylinder-shaped so far that the same is delimited by a cylindrical inner surface 4 and a likewise cylindrical outer surface 5, the two opposite side surfaces 6 being plane and mutually substantially parallel.
- reference numeral 7 designates an arbor which at one end has a stop member 8 and at the opposite end an axially movable clamping mechanism generally designated 9.
- this clamping mechanism includes a cage 10 axially movable along the arbor, as well as a nut 11, which is fastened with screws on a threaded end portion 12 of the arbor.
- the stop member 8 consists of a thickened portion of the arbor. This thickened portion as well as the cage 10 have plane shoulder surfaces 13 and 14, respectively, which extend perpendicularly to the geometrical, longitudinal axis of the arbor.
- Two cutting tools are shown schematically in the form of so-called slitting cutters designated 15. Slits or cuts may be milled by means of these cutters in the ring blanks 3, which are mounted on the arbor and fixed thereon by means of the clamping mechanism.
- a number of tangentially spaced grooves 16 extending axially along the arbor are recessed in the arbor in order to be able to house the cutters whilst they cut completely through the set of rings.
- Partially circular recesses 17 in the extension of the grooves 16 are recessed in the portion 8, which serve as a stop member.
- Analogous recesses 17' are also recessed in the cage 10.
- An important feature of the method according to the invention consists of using rings 3 as blanks for the manufacture, which rings individually have a volume which is large enough to house a plurality of finished components 1.
- the individual ring blank is assumed to be large enough to permit the manufacture often components.
- the individual ring blank is face machined on the two opposite sides 6 thereof.
- This machining which, in practice, can consist of face milling or face grinding, can be carried out in a conventional way, to an accuracy within the range 0.005-0.02 mm.
- two or more face machined ring blanks are put together one after the other along a common geometrical axis, and fixed in relation to each other while forming a set of rings with stable shape.
- twelve ring blanks are shown in such a set.
- the rings are threaded onto the arbor 7, and then the cage 10 is applied and tightened by means of the nut 11. Thanks to the fact that all the ring blanks have face machined, parallel side surfaces at the same time as the pressing surfaces 13, 14 extend perpendicularly to the longitudinal axis of the arbor, an immovable clamping of the rings in the set is achieved.
- all milling operations may be carried out by axial movements in relation between the ring set and the milling tool, whereby each surface or serration can be machined in one single pass.
- the tool and/or the ring set is/are transported in one single, unbroken motion from one end of the ring set to the opposite one.
- the ring set is given tangentially spaced and radially oriented through cuts, which separate the different components from each other.
- the components are intended to be included in tools for chip removing machining, they are usually manufactured in steel.
- the invention offers a possibility to carry out the requisite hardening of the steel before the above-mentioned machining operations are started.
- the unmachined ring blanks 3 already in the unmachined state may be submitted to hardening.
- the following advantages are won, the machining accuracy is improved, as well as that the comparatively large ring blanks facilitate and hasten the requisite handling in connection with hardening (the numerous, small components which are extracted from each ring blank require a handling which is more time-consuming).
- a significant advantage of the invention is that numerous components may be machined and extracted at the same time without having to be repeatedly moved between different machining stations and fixtures. This in turn ensures high accuracy of the components after all machining has been completed. In all essentials, all components become identical.
- the ring blanks 3 are cylinder-shaped and used for the manufacture of wedges which should have concavely arched surfaces 2 of the type that is shown in fig 1.
- Other components may, however, require differently shaped surfaces, e.g. plane surfaces.
- a final face machining is required when the components have been separated from each other.
- the invention is not limited to the embodiments illustrated schematically in the drawings. Thus, it is feasible to dispose the ring blanks in a set in which ring-shaped shims between adjacent ring blanks are included. In other words, the ring blanks do not need to be pressed in direct surface contact with each other as is shown in fig 2.
- ring blanks in the preferred embodiments, are placed concentrically in relation to a mutual geometrical axis - e.g. on an arbor common for all rings - it is also feasible to mount the rings without any requirement regarding concentricity.
- the above invention has been described in connection with components intended to be included in different types of tools for chip removing machining, the same may also apply for other arbitrary, small components irrespective of the material thereof.
